A device for conditioning the electrical signal generated by a vibration sensor for use of the conditioned signal by a computer-based data acquisition system utilizes a support body and circuitry for performing a series of operations upon the sensor-generated signal. The circuitry includes an input stage for receiving and amplifying the electrical signal generated by the vibration sensor to thereby develop an output electrical signal of the input, and further includes a gain stage for receiving and AC coupling the output electrical signal of the input stage and amplifying the output signal of the input stage by a predetermined factor and thereby developing an output electrical signal of the gain stage. A integrator receives and integrates the output electrical signal developed by the gain stage, and a filter receives and filters either the output electrical signal developed by the gain stage or the output electrical signal developed by the integrator to thereby develop an output electrical signal by the filter which is free of signal frequency above a preselected frequency range. A buffer receives and amplifies the output electrical signal of the input to thereby develop an output electrical signal of the device. The device further includes a sample/hold stage at which the output signal from the buffer can be collected and frozen as a sample signal for use of the frozen signal by the data-gathering system.
